PEA-SHELLER.

Specification of Letters Patent.

Patented Oct. 19,1909.

' Application filed July 2?, 1908. Serial No. 445,582.

especially arranged for being attached to a' kitchen table and in which the shelling operation is effected by crank actuated squeezing rollers, and it primarily has for its object to provide va machine of the character stated,

' fied form and novel arrangement more especially adapted for hulling green peas, in which the parts are especially designed for economically manufacturing the machine and which, when assembled can be conveniently worked by the operatorv for quickly separatin the peas from the pods without danger o crushing the peas.

With the above and other objects in view, my invention comprehends a pea huller or sheller embodying the peculiar construction of parts hereinafter fully described, specifically pointed out'in the appended claims and illustrated in the accompanying drawings, in which;-

Figure 1, is a perspective view of my improved constructlon of pea huller, and illustrates the manner in which it is used. Fig. 2, is a perspective view of the same, viewed Flg. 3, is a transverse section of Fig. 1. Fig.

4, is a cross section thereof'on the line Jr-4 on Fig. 3 looking in the direction of the arrow. Fig. 5, is a perspective view of the main casting or frame member. Fig. 6, is a similar view of the second coiiperating casting. Fig. 7, is a section of the combined gear crank and pod crushing roller, and, Fig. 8, is a face view of the discharge end of the machine. Fig. 9, is a face view of a simpliof my invention hereinafter described.

In the practical application of my invention', the body portion or frame of the ma chine is made up of cast metal and comprises two parts, one of which or includes a leg or standard 1 provided with parallel right angle bracket members 10-10 for clamping the machine onto the edge of a kitchen table or other support, the lower one of the said members 10 carrying a clamp screw 11 having a swiveled bearing head 12 as clearly shown in thefdrawings.

.The upper end of the casting a terminates one half section from an opposite direction to that of Fig. 1.

removing the screws 0 -0 the upper ends of which extend rearwardly and form ears 21 for straddling the upper bifurcated ends of the head portion 1.2 of the casting a and to which'they are pivotally joined by the stud pins 23-23 as clearly shown in Figs. 1 and 2, by reference to which it will be seen that the upper or bifurcated head 12 includes an integral cross or brace bar 15. The casting I) also includes a front wall 25, the upper edge 25 of which is in a horizontal plane substantially in line with the meetin faces of a pair of pea splitting rolls 3-3 fbr the reason presently explained. The front wall 25 extends downwardly between the laterally beyondone of the end walls, its lower endbeing curved inwardly to form 0, the other part of which is formed by the inwardly curved extension 16 of the casting a and to firmly lock the two parts of the easing together, the meeting edges of the chute or spout have pendent apertured lugs c-"c' that receive the securing screws 0 -0 as shown.

So far as described, it is ap arent that by om the main casting lugs c, the member I) can be readily swung up so the rolls 3-3 can be readily fitted into position or removed as may be desired. 1

The rolls 3-3 are made of rubber through which the shaft 30 is tightly fitted and the short protruding portions of said shaft form end walls 2 and it also extends.

of an inclined chute or spout bearings 30-30 adapted to lie in the semicircular recesses 14 and 24. Theshafts need not be, but preferably are, cast as a unit with their gears, and the lower shaft is integrally made with a crank handle whereby motion is imparted. I

The rolls are each corrugated lon 'tudinally and transversely, whereby to orm a series of clearly defined angular projections 32-32, the transverse corrugation of the two rolls being however relatively such that the projections 320m one roll will alternate with the like projections on the other roll. This manner of forming the rolls, I have found very desirable since a perfect gripping of the ends of the pods is insured and in a substantially transverse direction as the pods enter between the rolls, such action on the pods causing them to snap or split almost the instant they begin to pass between the rolls and thereby insures a perfect separa= tion of the peas from .the pods, the latter passing through the rolls and discharging into a suitable receptacle while the peas drop into the chute and are discharged laterally into, a bowl or receiver.-

By having the upper edge of the front wall 25 in line with the gripping edge of the rolls, it follows that the said edge can be conveniently utilized as a rest for the pods andfor properly guiding them to the rolls during the operation of shelling.

The casing may be cast in one piece and shaft bearing apertures drilled, and this method together with all covering may aggregate less expense than the preferred style of manufacture although both forms I find advantageous.

From the foregoing, taken in connection with the accompanying drawings, it will be readily apparent that by combining the several parts as described and shown, the construction of the complete sheller is rendered very simple and can be manufactured at a minimum cost, and since the parts are all of metal there is little or no danger of their beco ming broken or disarranged.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is p 1. A pea sheller, comprising the following elements in combination, a main casting comprising a standard having means at the lower end for clamping to a table or other support, a head portion at the other end, said head portion consisting of a bifurcated member that constitutes the back wall of the sheller said bifurcated member having an inwardly curved'member, the upper end of the bifurcated portion terminating in ears, the inner edge of the said bifurcated portions having half bearings, the cooperating casting that forms the front member of the head, said casing comprising closed sides, the upper ends of which terminate in ears for plvotally engaging the ears of the bifurcated portion and having half bearin 's for opposing the bearings on the bifurcate portions, the said casting having a front portion terminating in a downwardly extended inwardly curved member for opposing the curved member on the other casting, means for forming the curved ends of the two castings together, superimposed rollers mounted in the bifurcated back wall and crank and gear connections for the said rollers, said rollers having rows of blunt, pyramidal teeth in staggered arrangement.

2. A pea sheller comprising the following elements in combination, a main support having means for securing it to a table or other sup ort and having a head portion formed of bifurcated vertically extended members and an inwardly curved and downwardly inclined portion, the bifurcated members being joined by a cross piece at the upper end and terminating in apertured ears, a second casting comprising side walls having ears for pivotally engaging the ears in the bifurcated ends of the other casting, and having the front walls, whose upper edge is in a plane with the shelling surface of the shelling rollers, said front wall terminating in a downwardly inclined and inwardly curved member, means for clamping the curved portions of the two castings together whereby to form a laterally projecting chute and the pair of superimposed rollers mounted in the bifurcated end of the main casting, said rollers having integral gears and one of said gears also having integral crank member, said rollers havin rows of blunt, pyramidal teeth in staggere arrangement.
